The island
A casebook built from place, records and motive
Cala Sombra lives by tides, weights and watch schedules. Each case now begins inside the working coast before its harbour registers, salt tallies and astronomical observations expose contradictions no alibi can smooth away.
Evidence you will examine
- Atmospheric case-opening dossiers
- Verified suspect statements and record extracts
- Harbour, quarantine and observatory records
- 1,540 fillable logic-grid cells
Enter the scene. Test every statement. Name the killer.
Each self-contained investigation now opens with an atmospheric dossier. Suspect statements and record extracts repeat verified numbered clues from the case file, so the added suspense never changes the fair-play solution. Mark the interactive grids as you read, use a hint only when you choose, then compare your deduction with the complete solution.
